Major Rate Hikes Hit UK Mortgages on Tuesday 31 March 2026 - HSBC, Barclays Lead Sharp Increases

Major Lenders Drive Mortgage Rates Higher in Coordinated Move

Tuesday 31 March 2026 brought a wave of significant mortgage rate increases across the UK market, with four major lenders implementing substantial hikes that will impact borrowers nationwide. HSBC led the charge with increases of up to 60 basis points, whilst Barclays delivered some of the most dramatic moves we've seen in recent months, pushing rates up by over 100 basis points in several categories.

The coordinated nature of today's increases suggests lenders are responding to broader market pressures, with the Bank of England base rate sitting at 3.75%. These moves represent a significant shift in the competitive landscape and will have immediate implications for anyone looking to secure a new mortgage deal.

HSBC Implements Broad-Based Rate Increases

HSBC made sweeping changes across their entire mortgage range, with the most significant increases affecting new customer products. Their First Time Buyer rates saw substantial hikes, with the 2-year fix at 60% LTV jumping from 4.57% to 5.17% - a 60 basis point increase. The corresponding 5-year fix rose from 4.68% to 5.18%, representing a 50 basis point rise.

Home movers weren't spared either, with HSBC's 2-year fix at 60% LTV increasing from 4.49% to 5.09% (60bps), whilst the 5-year equivalent moved from 4.52% to 5.02% (50bps). These increases were mirrored across all LTV bands, with the pattern consistent throughout HSBC's residential range.

Existing customers faced more modest increases but still significant enough to impact refinancing decisions. HSBC's existing customer switching products saw 2-year rates rise by 40 basis points and 5-year rates by 30 basis points across most LTV bands.

The buy-to-let sector experienced similar treatment, with HSBC's Purchase BTL 2-year fix at 60% LTV rising from 4.43% to 5.03% (60bps), and the 5-year fix moving from 4.18% to 4.78% (60bps). International mortgage rates also increased substantially, with some products seeing 60 basis point rises.

Barclays Delivers Market's Most Dramatic Increases

Barclays implemented the day's most eye-catching rate changes, with some products increasing by over 100 basis points. Their existing customer switching 2-year fix at 60% LTV soared from 3.52% to 4.80% - a massive 128 basis point increase that fundamentally alters the value proposition for Barclays' current borrowers.

New purchase customers faced similarly dramatic hikes. The Barclays 2-year fix at 60% LTV for new purchases jumped from 3.55% to 4.60% (105bps), whilst their 5-year equivalent rose from 3.75% to 4.80% (105bps). Even their 10-year fix increased substantially, moving from 4.72% to 5.35% (63bps).

Remortgage customers weren't spared, with 2-year fixes at 60% LTV rising from 3.62% to 4.66% (104bps) and 5-year fixes jumping from 3.68% to 4.81% (113bps). The scale of these increases suggests Barclays is either responding to significant funding cost pressures or making a strategic decision to reduce mortgage lending volumes.

At higher LTV bands, Barclays continued the aggressive repricing. Their 75% LTV new purchase 2-year fix increased from 3.78% to 4.66% (88bps), whilst remortgage products at the same LTV saw rises from 3.75% to 4.68% (93bps). These changes position Barclays well above current market leaders and likely out of contention for most price-sensitive borrowers.

Nationwide Takes More Measured Approach

Nationwide implemented more modest but still significant increases across their range. Their market-leading 2-year fix at 60% LTV for home movers rose from 4.25% to 4.55% (30bps), whilst maintaining its position as the current market leader at this rate.

First-time buyers saw Nationwide's 2-year fix at 60% LTV increase from 4.55% to 4.85% (30bps), with the 5-year equivalent rising from 4.80% to 5.10% (30bps). The building society maintained consistency across most products, with 25-30 basis point increases being the norm.

Higher LTV products followed similar patterns. At 90% LTV, Nationwide's first-time buyer 2-year fix rose from 4.85% to 5.15% (30bps), whilst their 5-year fix increased from 4.95% to 5.25% (30bps). Even at 95% LTV, increases remained relatively contained, with the first-time buyer 2-year fix rising from 5.40% to 5.55% (15bps).

NatWest Rounds Out the Day's Increases

NatWest completed the quartet of major lenders implementing rate increases, though their changes were more targeted than the across-the-board hikes seen elsewhere. Their new purchase 2-year fix at 60% LTV rose from 4.52% to 4.80% (28bps), with the 5-year equivalent increasing from 4.69% to 4.97% (28bps).

Remortgage customers faced slightly larger increases, with NatWest's 2-year fix at 60% LTV jumping from 4.56% to 5.02% (46bps). At higher LTV bands, the pattern continued, with 75% LTV remortgage rates seeing significant increases - the 5-year fix rose from 4.74% to 5.41% (67bps).

Market Impact and Current Competitive Landscape

These coordinated rate increases fundamentally alter the competitive dynamics in the UK mortgage market. Nationwide emerges as the clear winner in terms of competitive positioning, with their home mover 2-year fix at 4.55% (60% LTV) now representing exceptional value compared to rivals.

The increases create significant challenges for borrowers whose current deals are expiring. Those who might have expected to secure rates in the high-3% or low-4% range now face a reality where sub-4.5% rates are increasingly rare, except from select lenders like Nationwide.

For existing customers of the affected lenders, particularly Barclays and HSBC, the decision-making process becomes more complex. The loyalty discounts that might have made staying put attractive have been eroded by these substantial rate increases, making switching to competitors like Nationwide increasingly compelling.

What This Means for Different Borrower Types

First-time buyers face a particularly challenging environment following today's changes. With HSBC's first-time buyer rates now starting above 5% for most LTV bands and Barclays effectively pricing themselves out of this market, the pool of competitive options has narrowed considerably.

Home movers have slightly more choice, with Nationwide's rates remaining competitive despite today's increases. However, the gap between the best and worst deals has widened dramatically, making thorough mortgage comparison more critical than ever.

Existing customers of the affected lenders face difficult decisions. HSBC customers, whilst seeing smaller increases than new customers, still face rate rises that make exploring alternatives worthwhile. Barclays customers, particularly those on existing customer products, should urgently review their options given the dramatic rate increases implemented today.

Buy-to-let investors haven't escaped the rate increases, with HSBC's BTL products seeing substantial rises across all categories. The 60 basis point increases on many BTL products will impact rental yields and investment calculations significantly.

Looking Ahead: Market Trends and Borrower Strategy

Today's rate increases represent more than routine pricing adjustments - they signal a more challenging environment for UK mortgage borrowers. The scale and coordination of these moves suggest lenders are responding to sustained pressure on funding costs or making strategic decisions about lending volumes.

For borrowers currently in the market, these changes reinforce the importance of acting quickly when competitive rates become available. The gap between the best and worst deals has widened significantly, making broker advice and comprehensive market comparison increasingly valuable.

Those with deals expiring in the coming months should begin exploring options immediately, particularly if they're current customers of the lenders implementing the most significant increases. The assumption that loyalty will be rewarded with competitive rates has been challenged by today's moves.
